Interest has been expressed in using silver sagebrush (Artemisia cana Pursh ssp. cana) in restoring the Northern Mixed Prairie in Saskatchewan. The objectives of this study were to determine the effects of seedbed manipulation treatments and autumn or spring sowing on establishment of silver sagebrush on sites previously seeded to native, perennial grasses. Seeds (achenes) were sown by broadcasting at 20 pure live seeds m"2.Seedling emergence ranged from 5 to 6 % of seeds sown. Most seedlings emerged in May and June; no seedlings emerged after July or in the second year after planting. Seventy-four to 84% of emerging seedlings survived the first growing season with 96 to 98% of these seedlings establishing. On upland sites, seedling emergence (1.1 seedlings m'2 SE ± 0.1) and establishment (0.9 seedlings m 2 SE ± 0.1) were similar between autumn and spring sowing and among seedbed manipulation treatments. On lowland sites, seedling emergence (1.4 seedlings m 2 SE+0.2) and establishment (0.8 seedlings m'2 SE ± 0.2) were similar between autumn and spring seeding. Density of seedlings establishing was greatest when the seedbed was tilled. Establishment of silver sagebrush appears primarily limited by low numbers of seedlings emerging, indicating very specific safe site requirements for this shrub. (0.9 plantulas m_2 ES t 0.1) fueron similares entre las siembras de otoiio y primavera y entre los tratamientos de manipulacion de la cama de siembra. En los sitios bajos la emergencia de plantulas (1.4 plantulas m2 ES ± 0.2) y establecimiento (0.8 plantulas m 2 ES ± 0.2) fueron similares entre las siembras de otoi o y primavera. La densidad de plantulas establecidas fue mayor cuando la cama de siembra fue labrada. El establecimiento de "Silver sagebrush"parce ser limitado principalmente por el bajo numero de plantulas que emergen, indicando que este arbusto tiene requerimientos de sitio seguro muy especificos. En lugares donde se tienen establecidos zacates perennes no se requiere un disturbio drastico para establecer el "Silver sagebrush". Se recomienda sembrar el "Silver sagebrush"a fines de otono, cuando las temperaturas estan consistentemente bajo 0°C o a inicios de primavera, inmediatamente despues de que la nieve se derrite.
